Description

Technical Field

[0001] This utility model relates to the field of urea tank counterweight technology for loaders, specifically a loader counterweight that can hold a urea tank. Background Technology

[0002] A loader counterweight is a device used to maintain the stability of a loader and prevent it from tipping over during operation. It is typically installed at the rear of the loader and balances the load at the front by adding weight, ensuring the machine's stability during operation.

[0003] The urea tanks on existing loaders are often placed separately, which takes up a lot of space. Moreover, loaders work on rough dirt roads at construction sites, where the urea tanks are often subjected to a lot of bumps. These bumps are very likely to cause damage to the urea tanks, causing the liquid inside to spill out. Utility Model Content

[0004] The purpose of this utility model is to provide a loader counterweight that can accommodate a urea tank, in order to solve the problem mentioned in the background art that the urea tank on the loader is often placed separately, which occupies a lot of space. Moreover, the loader works on the bumpy dirt roads of the construction site, and the urea tank is often subjected to great bumps. These bumps are very likely to cause damage to the urea tank, causing the liquid inside the urea tank to spill out.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a loader counterweight for placing a urea tank, comprising a main counterweight block and a first counterweight block and a second counterweight block fixedly installed at both ends of the main counterweight block. First sliding grooves are provided on the side walls of both the first and second counterweight blocks. A fixing component for installing and fixing the urea tank is provided at the upper end of the first counterweight block. A buffer component to prevent the urea tank from being damaged by impact is provided on the first counterweight block. A displacement component to mitigate the impact force of the first counterweight block is provided at the lower end of the first counterweight block.

[0006] Preferably, the fixing component includes a first chamber formed on a first counterweight, two second sliding grooves formed on the first chamber, a plurality of limiting grooves formed on the first counterweight, a urea tank shell slidably mounted on the two second sliding grooves, a plurality of mounting grooves formed on the side wall of the urea tank shell, a limiting block slidably mounted on each of the plurality of mounting grooves, a first spring provided between the limiting block and the mounting groove, and an electromagnet fixedly mounted on each of the plurality of mounting grooves.

[0007] Preferably, the buffer assembly includes a urea tank body movably installed inside the urea tank shell, the upper end of the urea tank body is provided with a bottle stopper and two handles, a dustproof cotton is bonded between the urea tank body and the urea tank shell, and a plurality of second springs are provided between the urea tank body and the urea tank shell.

[0008] Preferably, the displacement assembly includes a displacement box fixedly installed at the lower end of the first counterweight, a displacement groove is provided on the displacement box, a base plate is slidably installed on the displacement groove, a plurality of third springs are provided between the base plate and the displacement groove, an airbag is provided in the middle of the displacement box, a connecting pipe is provided between the airbag and the displacement box, and a push rod is fixedly installed on the side wall of the base plate.

[0009] Preferably, the cross-sectional dimensions of the limiting block and the limiting groove are the same.

[0010] Preferably, the airbag is located at the middle of the displacement box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Under the action of the first chute, the counterweight device is installed on the loader. With the cooperation of the urea tank shell, the second chute, the first chamber, the mounting groove, the limiting groove and the first spring, the urea tank shell is fixed in the first chamber. With the cooperation of the controller and the electromagnet, the electromagnet generates a force to attract the limiting block, causing the limiting block to compress the first spring and enter the mounting groove. At this time, the urea tank shell can be taken out from the first counterweight block, which is convenient for the replacement and maintenance of the urea tank.

[0013] 2. When the loader is working on a dirt road, it will inevitably experience severe bumps. The second spring and dustproof cotton can alleviate the shaking of the urea tank body and prevent damage to the urea tank body caused by severe bumps. The dustproof cotton not only alleviates the shaking of the urea tank body caused by bumps, but also prevents dust or mud from falling between the urea tank body and the urea tank shell, which would prevent the second spring from working properly. With the cooperation of impact force, base plate, displacement groove, gas, connecting pipe and air bag, the air bag expands. The expanded air bag disperses and cancels the impact force on the base plate, preventing the impact force from damaging the urea tank body. With the cooperation of push rod and base plate, the friction between the push rod and the side wall of the first counterweight block is used to eliminate part of the impact force, indirectly reducing the impact force suffered by the urea tank body.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1 and Figure 2 A loader counterweight for placing a urea tank includes a main counterweight 1 and a first counterweight 11 and a second counterweight 12 fixedly installed at both ends of the main counterweight 1. First grooves 13 are provided on the side walls of both the first counterweight 11 and the second counterweight 12. A fixing component 2 for installing and fixing the urea tank is provided at the upper end of the first counterweight 11, preventing the liquid in the urea tank from spilling out due to bumps during loader operation. A buffer component 3 is provided on the first counterweight 11 to prevent the urea tank from being damaged by impacts. The buffer component 3 reduces the shaking of the urea tank caused by bumps, preventing damage to the urea tank shell and spillage. A displacement component 4 for mitigating the impact force of the first counterweight 11 is provided at the lower end of the first counterweight 11, greatly buffering the impact force at the lower end of the first counterweight 11 and preventing damage to the urea tank and leakage of urea liquid.

[0022] The fixing component 2 includes a first chamber 21 formed on the first counterweight 11. The first chamber 21 has two second sliding grooves 28. The first counterweight 11 has several limiting grooves 23. The urea tank shell 22 is slidably mounted on the two second sliding grooves 28. The side wall of the urea tank shell 22 has several mounting grooves 24. Each of the mounting grooves 24 has a limiting block 25 slidably mounted on it. The limiting block 25 is made of magnetic material. When the electromagnet 27 is energized, it can attract the limiting block 25. A first spring 26 is provided between the limiting block 25 and the mounting groove 24. Each of the mounting grooves 24 has an electromagnet 27 fixedly mounted on it.

[0023] The cross-sectional dimensions of the limiting block 25 are the same as those of the limiting groove 23. At this time, the limiting groove 23 can limit the limiting block 25 to prevent the limiting block 25 from becoming loose or falling off.

[0024] In this embodiment: the counterweight device can be installed on the loader via the first slide groove 13. At this time, the urea tank shell 22 is placed in the first chamber 21 via the second slide groove 28 until the mounting groove 24 and the limiting groove 23 correspond. At this time, the limiting block 25 enters the limiting groove 23 under the action of the first spring 26, thereby fixing the urea tank shell 22 in the first chamber 21. If it is necessary to remove the urea tank shell 22, the electromagnet 27 is energized by the controller. At this time, the electromagnet 27 generates a suction force on the limiting block 25, causing the limiting block 25 to compress the first spring 26 and enter the mounting groove 24. At this time, the urea tank shell 22 can be removed from the first counterweight block 11, which facilitates the replacement and maintenance of the urea tank.

[0025] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 3-5 The buffer assembly 3 includes a urea tank body 31 movably installed inside the urea tank shell 22. The upper end of the urea tank body 31 is provided with a bottle stopper 32 and two handles 33. A dustproof cotton 34 is bonded between the urea tank body 31 and the urea tank shell 22. The dustproof cotton 34 can not only relieve the shaking of the urea tank body 31 caused by bumps, but also prevent dust or dirt from falling between the urea tank body 31 and the urea tank shell 22, causing the second spring 35 to malfunction. Several second springs 35 are provided between the urea tank body 31 and the urea tank shell 22.

[0026] The displacement assembly 4 includes a displacement box 41 fixedly installed at the lower end of the first counterweight 11. The displacement box 41 has a displacement groove 42. A base plate 43 is slidably installed on the displacement groove 42. Several third springs 44 are arranged between the base plate 43 and the displacement groove 42. An airbag 45 is arranged in the middle of the displacement box 41. A connecting pipe 46 is arranged between the airbag 45 and the displacement box 41. A push rod 47 is fixedly installed on the side wall of the base plate 43.

[0027] The airbag 45 is located at the middle of the displacement box 41. When the gas in the displacement box 41 is compressed to the airbag 45 through the connecting pipe 46, the airbag 45 expands. The expanded airbag 45 then disperses the force on the base plate 43, thus mitigating some of the impact force.

[0028] In this embodiment: When the loader is working on a dirt road, it will inevitably experience severe bumps. If no measures are taken, the urea tank will certainly be damaged. At this time, the second spring 35 and the dustproof cotton 34 can alleviate the shaking of the urea tank body 31, preventing damage to the urea tank body 31 caused by severe bumps. The dustproof cotton 34 not only alleviates the shaking of the urea tank body 31 caused by bumps, but also prevents dust or mud from falling between the urea tank body 31 and the urea tank outer shell 22, causing the second spring 35 to malfunction. Because when the loader is working, the counterweight inevitably comes into contact with the soil, causing the first counterweight 11 to be impacted. At this time, the impact force will drive the bottom plate 43 to move within the displacement groove 42, thereby moving the displacement groove... The gas inside 42 is squeezed into the airbag 45 through the connecting pipe 46, causing the airbag 45 to inflate. At this time, the bottom plate 43 comes into contact with the inflated airbag 45. The inflated airbag 45 disperses and cancels the impact force on the bottom plate 43, preventing the impact force from damaging the urea tank body 31. At this time, the push rod 47 on the side wall of the first counterweight 11 moves upward due to the displacement of the bottom plate 43. It eliminates part of the impact force through the friction with the side wall of the first counterweight 11, indirectly reducing the impact force suffered by the urea tank body 31. When the impact force disappears, the bottom plate 43 returns to its original shape through the action of the third spring 44, allowing the gas inside the airbag 45 to re-enter the displacement groove 42, so that the impact force can be buffered again through the displacement component 4.
